SfChart Stream

[p.b.]

Dear Sir or Madam,
in my current project the SfChart (With a FastLineSeries) is used to plot data. This data comes at a very high rate (in the end each 1ms) and the SfChart gets very fuzzy and slow. Is it possible to use a stream instead of an ObservableCollection so that only the last few points are plotted and the others are ignored?
Thank You

regards
Peter Burkert

Hi Pieter,

 

Thanks for using Syncfusion products.

 

We would like to suggest you that, you can use FastLineBitMap Series for Fast performance instead of FastLine Series as shown in the given code snippet

Code Snippet [Xaml]:

<chart:FastLineBitmapSeries   Label="First" XBindingPath="Date" YBindingPath="Value" LegendIcon="SeriesType" StrokeThickness="2"/>

 

Also when you set Zooming Factor property of ChartAxis then you can able to see only the last few plotted points as shown in the given code snippet

Code Snippet[Xaml]:

<chart:CategoryAxis LabelFormat="hh:mm:ss" ZoomFactor="0.75" >

 

We have prepared the sample based on your requirement. Please download it from the given below location.

How I using FastLineBitmapSeries from the C# code - without XAML - all my charts are generated dynamically and are not using XAML. I can't find any reminder about FastLineBitmapSeries in code documentation
